I am building a 3" vertical boiler with a centre flue with cross tubes. When talking with a wise old gent at a show last year he advised me that if I were to build such a boiler that I should do a hydraulic test on the flue and cross tubes before the assembly is silver soldered into the main barrel. The flue is 1"diameter. I am quite familiar with the mechanics of hydraulic testing but how do I go about sealing off the flue tube please. The tube is already cut to the required length.
